<p>The invention discloses a floodlight lighting apparatus, a lighting device, and a method for lighting floodlight. Before the power supply circuit starts any movement, the installation of the output terminal of the floodlight to the power supply circuit is detected. According to the detecting result, a suitable mode is adopted to control the movement of the power supply circuit, thereby being more secure. The LED lighting device comprises a power supply circuit used for installing the floodlight to the output terminal to light the floodlight, an installing detecting circuit having a detecting movement and a detection-stopping movement, with the detecting movement used for detecting whether the LED lamp has been installed to the output terminal of the power supply circuit or not while the detection-stopping movement used for stopping the detecting movement mentioned above during the lighting process of the LED lamp, and a control circuit used for making the power supply circuit carry out secure movement, when the LED lamp, detected by the installing detecting circuit, has not been installed to the output terminal of the power supply circuit.</p> |
